I Have heard good results with the HM oils...I have a Toyota 3.0 V6...Which one has the best package between MOBIL, VALVOLINE or CASTROL....THanks
quote:Because it has the best additive package and best base oil of all the name brand HM oils. I'm currently using SuperTech HM synthetic blend in my Olds van (146,000 miles). Made by Warren Dist, this oil has a good add pack, good specs, and some Group III base oil in it. And it's less expensive than the name brand HM oils which are all Group II or Group I/II.

quote:If your suggesting it's comprised entirely of group II or II+ base oil I recommend taking a look at the MSDS . I like the Mobil HM blend, it has some PAO and nice additive pack and the Citgo Ultra Life " 200ppm boron " and look forward to seeing the Havoline HM Syn Blend when it becomes available even though it might have group III instead of PAO , were talking lower cost oils here and all around 2 bucks a quart . The Castrol looks weak on paper but does very well as does the Pennzoil HM

quote:The PAO is for enhanced cold weather performance for the most part .Think of it as an additive here but the PAO does not help seals in a HM oil . I'm not certain all these HM oils for sure even use a small amount of Ester basestock for seal conditioning at this point .I think there are around 4-7 additives and mixes of them used for the seals to include special VII's.
Originally posted by DSteven: Hey Motorbike- Is the maxlife the only one to have PAO? It is what, ~22% PAO? They told me they use a true synthetic to get the seal conditioners to the leaks....maybe that is what does it?.. I
